Hey guys, new to here but not completely new to the forums.
I installed a 2.3 FRPP rear feed whipple on my '13 5.0 a few months back. I've Been messing with it for a while now because I'm shredding supercharger belts. I can drive it around town just fine but at high rpms (6500-7000) I'm tearing them up.
I'm 99.9% sure my supercharger pulley is out of alignment. I've tried schooching up the intercooler/intake manny on the bolt holes and spaced between the pulley and hub. I once spaced it about 6mm just to see if I could align the belt right where I wanted it and succeeded. I didn't break belts at 7500rpm and managed to tune it properly. The lip of the pulley didn't sit on the hub though (spaced too much) and I had a horrible shearing incident of the pulley bolts haha. I also grinded all the bosses down completely flush to the timing cover and sanded the bejesus out of them.
I'm going to look into getting a custom spacer made so that pulley lip can sit on the supercharger hub but I just can't accept that my kit out the box was 6mm off.
Has anyone else had an issue like this?
Does whipple sell different offset pullies? I tried to get some info out of whipple but they didn't have much. I just bought a few 2.5mm spacers from them but I'm sure one of those won't change anything. 2mm in there now vs a 2.5mm.
Thanks
